RFQ - Water Vapour Analyser

The National Physical Laboratory (NPL) is the UK's National Measurement Institute and is a world-leading centre of excellence in developing and applying the most accurate measurement standards, science, and technology available. The National Physical Laboratory (NPL) requirement is for a water vapour analyser, with the following capabilities:

1. capable of accurately measuring water vapours (see specification for amount fractions) in pure oxygen gas. 2. The analyser shall be CE/UKCA certificated. 3. Possibility to be networked and remotely accessed (minimum 100-1000 Base-T Ethernet) 4. Have a serial RS232/485, Modbus TCP connectivity. 5. Required to operate at standard UK mains power supply (230Vac, 50Hz). 6. Analog output (4-20 mA or 0-10 Vdc) is required to allow connectivity to exiting automatic analysers and LabView integration. 7. A local data storage (e.g. on flash drive) is desirable. 8. Inlet pressure: 2-9 bar a 9. Flow rate 0.05-1.5 slpm 10. Gas temperature up to 60⁰C 11. Wide dynamic range: over four orders of magnitude (see specification)
